Aircraft Loads Assessment for Windmilling Sustained Engine Imbalance:Analysis Methodology and Case Study Hugo Marcelo Nunes
Aircraft Materials and Analysis addresses aircraft design, mechanical and structural factors in aviation, flight loads, structural integrity, stresses, properties of materials, compression, bending, and aircraft fatigue. Detailed analysis of the failure processis provided. This authoritative guide examines materials used in aircraft construction such as aluminum, steel, glass, composite, rubber, and carbon fiber. Maintenanceprocedures for corrosion and aging aircraft are discussed and methods of inspection such as nondestructive testingand nondestructive inspection are described. Accident investigation case studies review aircraft design, materialbehavior, NTSB findings, safety, stress factors, and human factor involvement. End-of-chapter questions reinforce thetopics covered in this practical resource. Aircraft Materials and Analysis covers: * The aircraft--standards for design, structural integrity, and system safety * Aircraft materials * Loads on the aircraft * Stress analysis * Torsion, compression, and bending loads * Aircraft riveted joints and pressure vessels * Heat treatments of metals * Aircraft fatigue/aircraft material fatigue * Aircraft corrosion * Dynamic stress, temperature stress, and experimental methods * Composites * Nondestructive Testing (NDT) * Aviation maintenance management * Case studies and human factors

Fatigue of the pressurized fuselages of transport aircraft is a significant problem all builders and users of aircraft have to cope with for reasons associated with assuring a sufficient lifetime and safety, and formulating adequate inspection procedures. These aspects are all addressed in various formal protocols for creating and maintaining airworthiness, including damage tolerance considerations. In most transport aircraft, fatigue occurs in lap joints, sometimes leading to circumstances that threaten safety in critical ways. The problem of fatigue of lap joints has been considerably enlarged by the goal of extending aircraft lifetimes. Fatigue of riveted lap joints between aluminium alloy sheets, typical of the pressurized aircraft fuselage, is the major topic of the present book. The richly illustrated and well-structured chapters treat subjects such as: structural design solutions and loading conditions for fuselage skin joints; relevance of laboratory test results for simple lap joint specimens to riveted joints in a real structure; effect of various production and design related variables on the riveted joint fatigue behaviour; analytical and experimental results on load transmission in mechanically fastened lap joints; theoretical and experimental analysis of secondary bending and its implications for riveted joint fatigue performance; nucleation and shape development of fatigue cracks in riveted longitudinal lap joints; overview of experimental investigations into the multi-site damage for full scale fuselage panels and riveted lap joint specimens; fatigue crack growth and fatigue life prediction methodology for riveted lap joints; residual strength predictions for riveted lap joints in a fuselage structure. The major issues of each chapter are recapitulated in the last section.

A Nazi´s Nazi, SS Generalleutnant von Bassenheim has no intention of surrendering. And Lieutenant Commander Atsugi, an Imperial pilot with nothing left to live for, wants nothing less than total revenge. With Axis powers facing defeat, the two men set out on a suicide mission in a submarine aircraft carrier with two nuclear weapons on board and two Seiran fighters destined to drop their loads on American cities. In a cat-and-mouse game spanning the globe, one OSS officer and a team of naval aviators and ship commanders race against the clock to find and destroy the rogue submarine. 1. Language: English.

The U.S. military requires the ability to rapidly deploy troops, equipment, and materials anywhere in the world. Recent operations have brought attention to the need to utilize austere, unsurfaced, and sometimes sub-standard airfields within a theater of interest. These airfields may require additional taxiways and aprons. One option for the rapid construction of such is airfield matting systems. The focus of the work for this thesis was commercially available airfield matting systems to support large military transport aircraft, such as the C-17. Several test sections with differing strength soils were built with chosen mats tested in an elimination method, using a load cart that simulates contingency loading of one main gear of the C-17. Matting systems were evaluated based on logistical and assembly requirements, and deformation and damage sustained during traffic. A modeling effort was performed to investigate the potential of a simple model to predict the response of these matting systems under full-scale testing.
25,000 feet above Malta - that is where the Spitfires intercepted the Messerschmitts, Macchis and Reggianes as they swept eastwards in their droves, screening the big Junkers with their bomb loads as they pummeled the island beneath - the most bombed patch of ground in the world. One of those Spitfire pilots was George Beurling, nicknamed ´´Screwball,´´ who in 14 flying days destroyed 27 German and Italian aircraft and damaged many more. Hailing originally from Canada, after hard training and combat across the Channel, Beurling finally made it to Malta in the summer of 1942. Malta Spitfire tells his story and that of the gallant Spitfire squadron, 249, which day after day climbed to the top of the hill to meet the enemy against overwhelming odds. The listener has almost the sensation of being in the cockpit with him, climbing to meet the planes driving in from Sicily, diving down through the fighter screen at the bombers, dodging the bullets coming out of the sun, or whipping up under the belly of an Me for a deflection shot at the engine. This is war without sentiment or romance, told in terms of human courage, skill and heroism. A classic, first published in 1943. 1. Language: English. Narrator: Roger Davis.
